I love what Greg Forster did to teach his daughter what church is on Sunday:
So I decided to try using the fundamental principle of the Calvinistic understanding of worship, which is that the worship service is not primarily something we do for God, that it’s something God does for us. God is actively working in every part of the service; we participate, of course, but we are receiving much more than we are giving—we are far more passive than active. So during each part of the service, I would tell Anya what God was doing. During the call to worship I would tell her, “God is saying hi to us!” During the sermon I would tell her, “God is telling us his Word!” During the benediction I would say, “God is blessing us!” From all this, Anya learned exactly one thing:
the pastor is God.
